Title: Removal of waxy material from oils
IPC: B04B1/20
Filed: 1962-05-29
Abstract: <PICT:0952722/C3/1> Waxy material is removed from oil by treating the oil to form a slurry having its liquid phase of lower density than its solid phase and separating the phases in an imperforate centrifuge bowl which gradually increases in internal diameter for at least a substantial portion of its length, forcing the waxy material, deposited under the action of centrifugal force at the inner surface of the bowl, axially in the direction of decreasing radius of the bowl into a region in which it is freed from entrained oil by washing with a solvent, removing the oil-free waxy material from the region, and withdrawing the oil from the bowl at its end of greater radius. Raw lubricating oil feed stock containing waxy material is dissolved in a suitable solvent.  The mixture is heated to bring the oil and wax components in solution and is then cooled sufficiently to form the required slurry.  The chilled slurry is introduced through an inlet 10 into a stationary unit 11, passes into a screw conveyer 14 via its rotary shaft 12 and out through ports 16 on to the surface of the conveyer and is impinged upon the inner surface of the bowl 20 rotating at a higher speed than the conveyer.  The bowl may be conical, or partly conical and partly cylindrical.  Due to its higher density the wax-containing solid material from the slurry is consolidated in a layer on the bowl inner surface by centrifugal force while the oil-containing liquid component overflows through ports 24 into a housing 26 from which it is withdrawn through a discharge outlet 28.  The solid material is swept by the conveyer blade 18 from the surface of the consolidated layer into a zone 30 and out through ports 32 into the casing 26 where it is withdrawn through a discharge outlet 34.  Wash-solvent may be introduced through a pipe 42 and forced through nozzles or ports 44 in the conveyer 14 to remove entrained oil from the solid material.  The cooling of the heated mixture may be by means of heat-exchange apparatus or by auto-refrigeration.  The temperature of the chilled slurry is maintained during centrifugation by coolant circulation about the bowl area. The process may be continuous or intermittent. A number of solvents are specified and results of de-waxing processes using propane as the solvent are given.

Filed: 1927-08-09
Abstract: 300,299. Imray, O. Y., (Soc. of Chemical Industry in Basle). Aug. 9, 1927. Dye preparations. - Dry solid preparations of dyestuffs suitable for dyeing cellulose acetate silk are made by evaporating to dryness in the presence of sulphite cellulose liquor a fine dispersion produced by stirring the dyestuff with water in the presence of saponin or a condensation product obtained from formaldehyde and a naphthalenesulphonic acid. Azo dyes, indophenols, and anthraquinone dyes are specified as suitable for treatment by this process. In an example, 1-amino-4-oxyanthraquinone is stirred with the condensation product of #-naphthalenesulphonic acid and formaldehyde until a sample introduced into water gives a homogeneous emulsion, sulphite cellulose lye is then added, and the mixture is evaporated to dryness. Saponin may be used instead of the #-naphthalenesulphonic acidformaldehyde condensation product, and similar preparations may be obtained from 1-amino-2- methylanthraquinone, 1 : 4 - diaminoanthraquinone, 1-amino-4-anilidoanthraquinone and 1- methylamino-4-anilidoanthraquinone. In a further example, acetate silk is dyed in vivid blue-red tints with a suspension obtained with the product from 1-amino-4-oxyanthraquinone. Specification 271,898 is referred to.

Title: Process for recovery of the inorganic constituents of molasses stillage
IPC: C01D7/30
Filed: 1949-08-12
Abstract: Alkali metal salts are recovered from molasses stillage which may be previously concentrated to 8-12 per cent of its original volume by injecting it in an atomised condition by means of air or steam into a preheated combustion chamber and combusting it p  with excess air such that the particles of stillage are kept in suspension until combustion is complete.  Preferably the stillage is emulsified with 2-10 per cent of fuel oil prior to atomisation to assist combustion. The combustion chamber, which may be that of a steam boiler may be preheated by injection of oil alone and an auxiliary burner not burning stillage may be employed to assist combustion, but if desired the furnace temperature may be kept low so that the ash residue does not melt but is removed as a solid which may be employed directly as a fertiliser or used as raw material for the production of purer potassium compounds.ALSO:A fertilizer containing for example 30-35 per cent potassium and 5-10 per cent sodium is obtained by injecting molasses stillage in an atomized condition by means of air or steam into a preheated combustion chamber where it is combusted with excess air such that the particles are kept in suspension until combustion to ashes is complete.  Fuel oil may be emulsified with the stillage before injection and an auxiliary burner may be provided.  It is preferred to keep the furnace temperature low so that the ashes can be removed as a solid residue applicable as a fertilizer.
